问题     For decades, Americans have taken for granted the United States’ leadership position in the
development of new technologies. The innovations (创新)that resulted from research and development during World War II and afterwards were【C1】______to the prosperity of the nation in the second half of the 20th century. Those innovations, upon which virtually all aspects of【C2】______society now depend, were possible because the United States then【C3】______the world in mathematics and science education. Today, however, despite increasing demand for workers with strong skills in mathematics and science, the【C4】______of degrees awarded in science, math, and engineering are decreasing.
    The decline in degree production in what are called the STEM disciplines (science, technology, engineering, and math)seems to be【C5】______related to the comparatively weak performance by US schoolchildren on international assessments of math and science. Many students entering college have weak skills in mathematics. According to the 2005 report of the Business-Higher Education Forum, 22 percent of college freshmen must take remedial (补习的)math【C6】______, and less than half of the students who plan to major in science or engineering【C7】______complete a major in those fields.
    The result has been a decrease in the number of American college graduates who have the skills,【C8】______in mathematics, to power a workforce that can keep the country at the forefront (前沿)of innovation and maintain its standard of living. With the【C9】______performance of American students in math and science has come increased competition from students from other countries that have strongly supported education in these areas. Many more students earn【C10】______in the STEM disciplines in developing countries than in the United States.
A)accelerating I)especially
B)actually J)future
C)closely K)led
D)contemporary L)met
E)courses M)procedures
F)critical N)proportions
G)declining O)spheres
H)degrees [br] 【C5】
选项
答案 C
解析 空格处前面为be动词，后面为形容词related，故空格处词汇应该为副词。根据句意，在科学、技术、工程、数学领域学位数量的减少与学龄儿童在数学和科学方面的国际评估的较差表现有关，而且关系应该比较密切。因此用副词closely。备选的副词中，actually和especially虽然放在此处句意也通顺，但是在表达相关性时，closely更为准确。
